Clean Up create_empty_ts.smk for Unused Components

Description

The create_empty_ts.smk rule currently writes empty_ts for all components that require foreign_key='efficiency', even if those components are not listed in model_structure["components"]. While this behavior does not break functionality, it is not clean and can be misleading.

To improve clarity and maintainability, this behavior should be revised.

Steps to Take

1. Filter foreign_keys_efficiency to exclude components not listed in model_structure["components"], following the approach used for foreign_keys_profile:

   # Drop the ones that are not listed in model_structure
   foreign_keys_efficiency = [
       fk
       for fk in foreign_keys_efficiency
       if fk["efficiency"].split("-efficiency")[0]
       in model_structure["components"]
   ]

2. Ensure that empty_ts_load, empty_ts_feedin, and empty_ts_efficiency can gracefully handle being empty dataframes when applicable.

Acceptance Criteria

• create_empty_ts.smk no longer writes empty_ts files for components not listed in model_structure["components"].
• empty_ts_load, empty_ts_feedin, and empty_ts_efficiency can remain valid but empty when appropriate.
• The pipeline runs cleanly without warnings or unnecessary outputs.
